re: split primaries in series and parallel.
If you'd like to view the SB-1000 circuit diagram, there's a scanned
image on one of my servers.

:Hello Vic,
:I have a Heath SB1000 which is designed for 120 or 240 volts, and
:it has a 110v fan.
:In the case of 240v AC supply, the two primary windings of T1
:are in series, and the fan is connected across one winding only
:ie from one end of the primary to the center-tap.
:Hope this helps
:Martin ZL1ANJ
